Greetings! I have what is probably a dumb question but I want to be sure. The datasheet for the AD9283 says the inputs are biased to 0.3*Vdd (approx 1 volt). I also see that there is a range of +/- 200mv. I plan on driving this ADC with AD8138 (single-to-differential amplifier). It has the ability to add a common-mode voltage to the differential output. What CM would make the ADC happiest (operating under least distortion)? Exactly 0.3*Vdd? My reading of the datasheet is to stay within 200mv (up or down) from 0.3*Vdd. If so, then I will bias the AD8183 to the same (approx) 1 volt. Could the Vrefout from the AD9283 be used as the CM voltage of the AD8138? Thanks in advance!
